San Diego building 'set standard for energy efficiency'

Ongoing attempts to make commercial structures in San Diego, California, more energy efficient are inspired by the pioneering efforts of the city's Ridgehaven Building.

This is according to the San Diego Union-Tribune, which describes the three-storey, 73,000 sq ft office building as "a showcase for energy efficiency".

In 1999, the Ridgehaven Building became the very first structure to receive Energy Star certification from the US Department of Energy and the US Environmental Protection Agency.

"At the time, it was a very big step," Robert Epler, a former member of San Diego's environmental department, told the newspaper.

Energy-saving measures installed at the Ridgehaven Building include low-energy heat pumps, a digitally-controlled ventilation system, reflective window films to reduce heat absorption and room occupancy sensors for the lighting.

"It's not a highly decorated building. It's a functional tool," Mr Epler added.

According to San Diego's City Hall, the Ridgehaven Building's energy-saving measures reduce the structure's annual expenditure by approximately $100,000 (£61,200).
